[Paraview] MPI performance and VGL error

2009-02-18 Thread Orlando Rivera
Dear all,


We have compiled paraview server  with  MPICH2 and parastation ,   when
we deploy the server  , it starts with no troubles , the clients
connects  easily as well .

However , when  we do some calculations , like a contour,   it takes
much more time (~3x)to represent the surfaces   as  when  using the
client  alone


Another thing that bothers us,  when I start the client  with  vglrun 
(through vglconnect  )   We get this warning :
[VGL] ERROR: Cannot obtain a Pbuffer-enabled 24-bit FB config on the
VirtualGL
[VGL]server.  This is most likely because the 3D X Server :1.2
[VGL]is not configured for 24-bit color or does not have accelerated 3D
[VGL]drivers installed.
 
but we have drivers installed and cmake found them .   

I don't know   whether these two problems are related or not , I would like

1)  a benchmark  or a way to determinate  that the server does in fact
internal calculations when using mpi

2) How to solve the client issue with VGL

our hardware is a Sun x4600 server with 16 CPU cores (8x2 opteron ) 
with   SLES  10 SP2   and  four Quadro FX5500 graphics cards.


Any help is  gladly appreciated,  request  if you  need more 
information form us

Thanks

[Paraview] Extract cell type from unstructured grid

2009-02-18 Thread Paul Edwards
Hello,

Does anyone know an easy way to extract all cells of a particular type from
an unstructured grid (without writing code either a plugin or python
script)?  I was thinking it be possible with the calculator and the number
of points in a cell but I can't get access to that.

Re: [Paraview] Transformation extraction from Transform filter

2009-02-18 Thread Juan Fernando Duque Lombana
Thank you Utkarsh!

I used a property iterator to get the names of the properties you suggested;
Finally with this lines of code I was able to get the information I needed:

 vtkSMProxyProperty *Transform_prop =
vtkSMProxyProperty::SafeDownCast(myFilters[0]-getProxy()-GetProperty(Transform));

 vtkSMProxy* myTransformProxy=Transform_prop-GetProxy(0);
 vtkSMDoubleVectorProperty *Position_prop =
vtkSMDoubleVectorProperty::SafeDownCast(myTransformProxy-GetProperty(Position));

 vtkSMDoubleVectorProperty *Rotation_prop =
vtkSMDoubleVectorProperty::SafeDownCast(myTransformProxy-GetProperty(Rotation));

Thank you!

Re: [Paraview] Extract cell type from unstructured grid

2009-02-18 Thread Moreland, Kenneth
Paul,

I don't know of any existing filter to do that, but a pretty simple 
programmable filter can do it.  Here is the script that will achieve it.  Just 
create a custom filter and copy this into the script.

input = self.GetUnstructuredGridInput() output = 
self.GetUnstructuredGridOutput() 
output.GetPointData().PassData(input.GetPointData()) 
output.GetCellData().PassData(input.GetCellData()) cellTypes = 
vtk.vtkUnsignedCharArray() cellTypes.DeepCopy(input.GetCellTypesArray()) 
cellTypes.SetName(Cell Types) output.GetCellData().AddArray(cellTypes)
If you plan to use this multiple times, you probably want to wrap this in a 
custom filter.

Re: [Paraview] MPI performance and VGL error

2009-02-18 Thread Moreland, Kenneth
I will have to guess at why, say, contour is running slower.  I can think of 
two possibilities (but not claiming that either is necessarily correct).


 1.  Perhaps the data is not distributed.  If the reader is naive (you didn't 
specify what data you were reading), it could be just loading all of it on node 
0.  The poor performance could simply be that the data is really being 
processed in serial.  Run the Process Id Scalars filter on the output of 
contour to make sure that the cells are distributed amongst the processes.
 2.  Some filters (contour included) need ghost cells.  When you add them, they 
will send a request up the pipeline to load another layer of ghost cells.  
Assuming the reader supports it, the reader will usually reload the entire data 
set from file on each process to include the ghost cells.  There is a good 
chance that reading the data from disk is taking a lot longer than contouring 
the data.  Open the timer log (Tools - Timer Log) and see how much time each 
component is taking.  If the contour filter is reported to run really fast (or 
missing from the timings if faster than the threshold) and the reader is 
running multiple times, then that is probably it.

As far as your problems with vglconnect, I am afraid I cannot be much help as I 
am unfamiliar with that hardware.  (Perhaps someone else on this list has run 
into this hardware.)  It sounds like the pvserver nodes are having trouble 
connecting to the appropriate X displays.  Usually this is a matter of getting 
your DISPLAY environment variables (or -display command line flags) correct.

[Paraview] vtkXMLStructuredGridWriter class

2009-02-18 Thread Rakesh Hammond
Dear all,

I am trying to write out a part of my *.vts file into a new *.vts file,
where the user can select the i,j,k.  In fact I would like to write out the
i and k for a given j.
In order to do this, I am using the vtkXMLStructuredGridWriter class, in
particular the 
SetWriteExtenthttp://www.vtk.org/doc/release/5.2/html/a01601.html#661ae15ae5c0963599148b55c6041ad0(int,
int, int, int, int, int) method.

The .vts file contains points data and 9 arrays of data such as velocity
etc.

If the SetWriteExtent method is called with (1 16 1 11 1 2) for example,
every thing works as normal and I can visualize the data using Paraview for
example.

However, if the argument is (1 1 1 11 1 2), the points are written out, but
the arrays containing velocity are not written - well the definitions are
written (Float data, etc) - but not the values.

What am i doing wrong here?  Incidentally I am on VTK-5.2
Perhaps, I am not using the write method, if thats the case can some one
please point me towards what method/classes I should be using?

Thanks,
Rakesh

[Paraview] Emissive polygons?

Hello,

I'm not sure if I'm using the proper terminology, but is it possible  
in ParaView to give polygons or 3d cells an emissive property for  
the lighting, so they give off light instead of reflecting it?

Re: [Paraview] Emissive polygons?

2009-02-18 Thread Moreland, Kenneth
I'm afraid not.  It looks like that functionality is not even support in VTK.  
Implementing light emission that is constant for whole objects would be pretty 
straightforward, but would require modifying code all the way to VTK's 
rendering layer.

Re: [Paraview] xdmf hdf5 gzip compressed data

2009-02-18 Thread Renato Elias
Hi Johannes,

as you're also working with Fortran, I think I can help you a little bit
more. I wrapped some files (
http://www.nacad.ufrj.br/~rnelias/paraview/xdmf/xdfm-files.zip) and Fortran
routines I use in my program to write the Xdmf as well as the HDF5. It's
also a cavity flow dataset (unstructured grid, 5 time steps partitioned in 4
parallel subdomains). Note that the Xdmf files are written using the
Fortran's FORMAT statement. I know it's a bit uggly but my data does not
vary between runs, so, why would I need to use a library with a bunch of
routines if just a couple of Fortran FORMATs solve my problem? Moreover,
FORMATs are quite portable between systems without the need to compile or
install anything else.

By the way, I loaded your files without any problem...

Just deleted your system path from the HDF5 DataItem reference, for example:

Original:

/home/johannes/workspace/XDMF/xdmf_data/LDCF/LDCF.h5:data/coordinates/x_v

Modified:
  LDCF.h5:data/coordinates/x_v

Voilá, it works ;o)
(thanks God)

Of course, the xdmf file, in this case, must be kept in the same directory
of the HDF5 files it makes references (I have no idea if Xdmf file could
point to HDF5 files in other directories...)

I hope it helps you

 Hi Renato,

 many thanks for your replay, I'd rather have it to do the mistakes myself,
 and be sure PV is able to process compressed files. Got to sell xdmf to my
 manager on Friday!

 We use a fortran based code to produce the hdf5 files, that fore we use the
 hdf5 APIs.

 I write the xdmf files with python script on my own, since we did not want
 to produce yet another dependency. The files I produce work well, if the
 h5-files are not compressed. I tried to export my case as xdmf from PV3.4
 this produces a new h5 and xdmf file. I tried to compress this new file with
 ' h5repack ', but the resultfile crashes also.

 I have attached a h5 file we produced. It is the well known Lid Driven
 Cavity Flow (uncompressed) together with txt-dump and my xdmf file.

 Maybe you have an idea were I go wrong.

 Kind regards

 Johannes



 Quoting Renato Elias rnel...@gmail.com:

  Hi Johannes,

 I use Xdmf/HDF5 in Fortran and my files are compressed. After reading your
 message I did a test in PV3.4 and the dataset was loaded without any
 problem. Are you sure that the problem is related to compression? Have you
 got success in loading uncompressed files? Are you writing your Xdmf files
 using the library or the files are being made by yourself?

Re: [Paraview] particletracer

2009-02-18 Thread Martin Uppman
Hi John,

I downloaded your dataset last night and just got tested it. But I get the
exact same error with your dataset as mine! Let me describe exactly
what/how I'm doing:

1. Loading the dataset
2. Selecting the dataset and create filter 'temporal cache'. Click Apply.
3. Creating a line from menu 'sources'. Modifying the line where I want to
have it. Click Apply.
4. Selecting my dataset go to filters and particletracer. In the new
window I'm choosing 'source' as input port. Under 'select source(s)' I'm
holding down the shift key and click on temporal cache and line. Then I
click OK.

5. Error appears! same as before:

ERROR: In ..\..\..\ParaView3\VTK\Filtering\vtkDemandDrivenPipeline.cxx,

Am I doing something totally wrong??

Cheers,

 Martin

  I've put a dataset here
  ftp://ftp.cscs.ch/out/biddisco/flowviz/damBreakMarin.zip

  try loading this in paraview, connecting a cache and then a line source.
  If you are able to generate animated particles then all is well and there
 is something wrong with your data.
  If not, then maybe somethig is wrong with paraview cvs and I'd better
 take a look at it.

  NB. The dataset supplied is not a very good example as the time variable
 increments as 0,1,2 etc, and in fact should be much smaller, the
 particles travel too far each step. I only just remembered after I
 uploaded it.

 Hi John,  the error messages about Multiblock Dataset is showing when
 I dont use a temporal cache on my input. I tried using just a line
 source for seed points and I dont get any errors about that. So the
 problem is: If I just use particletracer on my input and line soure I
 get error saying Dataset is Multiblock Dataset which is not required.
 If a use a temporal cache on my input and then make a line source as
 seed points and connecting the two using the particletracer, it gives
 error saying dataset is TemporalDataset which is not required. I dont
 have any idea have to come around this problem. Is there another way
 to follow 3d flow in a good manner? I've tried streamtracer but dont
 think you get a clear view.  ERROR: In

 vtkTemporalStreamTracer(0x1ff6cdf0) is of type vtkTemporalDataSet, but
 a vtkDataSet is required.   Cheers,  Martin Uppman

Martin   Looking at your earlier message it seems
 like you are setting the seed points using a MultiBlock datastructure.
 I don't think I've enabled support for multiblock seed points (I will
 do so after clicking send, but you won't get it for some time). Please
 try converting your seed points to a simple dataset and retry. The
 error message saying DataSet is required is on port 1 (seeds) - not
 port 0 (vector field) - I didn't notice this before. Sorry. Try unsing
 a line source to start and see if everything works. then move on to
 more sophisticated stuff.   JB  Sorry, but this doesnt make any
 sense to me. I have a 3D dataset with magnitude and velocity (X,Y,Z)
 for 13 time frames. And as you wrote, paraview internally converts
 multiple vktDataSets into a TemporalDataSet. But particle tracer
 requires multiple time steps, why does it then give error that a
 vktDataSet is required? A  vktDataSet, according to what you wrote, is
 just a single timestep.  Martin  Martin   A single
 timestep is a vtkDataSet, StremTracer generates streamline through a
 vector field for this data.  The ParticleTracer requires multiple time
 steps to advect particles through the field over time.  The particle
 tracer requests 2 time steps per iteration from it's input, internally
 paraview converts multiple vtkDataSets from the input into a
 TemporalDataSet.   JB Thanks you, I can now conenct the two sources. I
 tried on Windows and found this alternative if I want to use input
 or source in the particle tracer. When choosing source I could
 select both dataset and seed source. Problem on my Mac was that the
 dialog box was to small so I didnt find this option.  Btw what is the
 difference between vtkTemporalDataSet and vktDataSet? ParticleTracer
 requires vktDataSet which I dont have, is it possible to convert the
 dataset somehow. I can use filter StreamTracer on my dataset and
 because StreamTracer and ParticleTracer is based on the same physics,
 I should be able to visualize particles.   ERROR: In
